Blower resistor inspection

1. Blower resistor inspection

1. Visual inspection

1) Inspect whether air flow volume can be switched to the 4 levels between 1st and 4th when the fan speed control dial is operated.

2. Resistance measurement

1) Measure the resistance between the blower resistor terminals using a DMM.
